V8 the 4.3 was in some of the caprices IIRC, you have the LB9 for sure ( I hope you knew that)
You have to post a pic of your RPO sheet.
The L99 was used from 1994 thru 1996 - a whopping 3 years.

That's RPO 199 (one hundred ninety-nine), not L99. The order of the codes is alphabetical, followed by numerical.
